The client developed a cryptocurrency exchange platform, with high liquidity as well as plenty of functional features. The Exchange supported both spot and leverage exchange, with a leverage ratio up to 200 times that of Bitmex. Specifically, its Circuit mode was also encrypted in the exchange, together with 2-layer and 3-layer security, hot wallet and cold wallet were made available to serve users’ diverse needs.
